That is written 43. The lower, left, larger number is the base, the upper, right, smaller number is the exponent.
An exponent.
coefficient?

Most likely it is a logarithm.
That is written 43. The lower, left, larger number is the base, the upper, right, smaller number is the exponent.
In the expression 45 the 4 is the base and the 5 is the exponent.
Then, if the exponent is a positive integer, the value is 1 multiplied by the base repeatedly, exponent times. If the exponent is a negative integer then it is the reciprocal of the above value.In either case, it is NOT the base multiplied by itself an exponent number of times.

The expression 4x4x4x4x4 can be written in index notation as 4^5, where the base is 4 and the exponent is 5. When you raise a number to an exponent, it means multiplying the base by itself the number of times indicated by the exponent. Therefore, 4^5 is equal to 1024.
